METHODS The monkey is anesthetized by the intravenous administration of sodium
pentobarbital. Instead of the conventional eye speculum, which impairs ocular mobility in the …

METHODS Six Macaca muld tn monkeys, each weighing G-7 lb., were studied. 1Jnder general
anesthesia they had implanted: I) a coil of wire on one eye to measure eye movements, 2…

Saccadic eye movements are shifts in the direction of gaze that rapidly and accurately aim
the fovea at targets of interest. Saccades are so brief that visual feedback cannot guide them …

Brain stem signals that generate saccadic eye movements originate in the superior colliculus.
They reach the pontine burst generator for horizontal saccades via short-latency pathways …

The retrograde transport of horseradish peroxidase has been used to identify efferent cells
in area 17 of the macaque. Cells projecting to the lateral geniculate nucleus are small to …

The execution of normal saccadic eye movements was found to depend upon clearly visible
fixation points. Eye movements made in the dark or in an otherwise homogeneous field …

In the 16 years since we last summarized the behavior of the premotor elements that control
saccades, research has revealed shortcomings in previous formulations of the control …

METHODS Nine monkeys(Macaca nzula t ta), weighing between 2.5 and 4 kg, were
maintained in primate restraining chairs. During a recording session the head and neck were …

1. We studied the effect of temporarily inhibiting neurons in the caudal fastigial nucleus in two
rhesus macaques trained to make saccades to jumping targets. We placed injections of the …

▪ Abstract In general the cerebellum is crucial for the control but not the initiation of movement.
Voluntary eye movements are particularly useful for investigating the specific mechanisms …
